If we've learned anything this month, it's to beware the high slit dress!

First, the sartorially-gifted Zoe Saldana had her dress blow up at the London premiere of "Star Trek." Then, Millie Mackintosh had her own Marilyn Monroe moment at the BAFTAs. For the event, the "Made In Chelsea" star chose a black Sass & Bide gown, complete with two thigh-high slits. The simple red carpet number was stylish, but it revealed a major design flaw when the lightweight fabric lost a battle with the wind, forcing Mackintosh to hold the front panel down.

Our takeaway? If you're going to go for the "Angelegging" look, make sure you opt for a dress with a heavy fabric... especially when you're walking the red carpet in windy London.
